Top 10 US Pet Supplies Manufacturers: The Brands Behind the Pet Boom

Americans spend over $150 billion a year on their pets — more than on baby food, and more than many countries spend on entire industries. Behind that boom is a concentrated group of manufacturers, mostly headquartered in the US, that produce the food, treats, litter, and accessories filling pet bowls and toy bins worldwide.

1. Mars Petcare — The undisputed global leader in pet food, with brands including Pedigree, Whiskas, Royal Canin, Iams, Nutro, Greenies, Sheba, and Temptations. Mars Petcare also runs one of the world's largest veterinary hospital networks, giving it an unmatched view of pet health trends.

2. Nestlé Purina PetCare — The second-largest pet food company in the world and Mars' biggest rival. Purina's portfolio spans Purina ONE, Pro Plan, Fancy Feast, Beneful, Tidy Cats litter, and Beggin' Strips treats. Its St. Louis headquarters houses one of the industry's largest pet nutrition research facilities.

3. Hill's Pet Nutrition — A subsidiary of Colgate-Palmolive, best known for Science Diet and Prescription Diet. Hill's is the brand most recommended by veterinarians for therapeutic nutrition, making it a staple in clinics and a benchmark for clinical pet food quality.

4. General Mills (Blue Buffalo) — General Mills entered pet food in 2018 with its $8 billion acquisition of Blue Buffalo, now the leading natural pet food brand in the US. The brand built its reputation on "no chicken by-product meals, no corn, wheat or soy" positioning.

5. J.M. Smucker — The Ohio-based food company's pet segment included Milk-Bone, Meow Mix, Kibbles 'n Bits, 9Lives, and Rachael Ray Nutrish — a portfolio it sold to Post Holdings in 2025 to focus on coffee and consumer foods. The brands remain major shelf presences in US retail.

6. Church & Dwight — Known for Arm & Hammer, this consumer goods company is the US leader in cat litter with Arm & Hammer Clump & Seal, and makes FURminator grooming tools and other pet care products. Its baking-soda heritage extends into odor-control litter technology.

7. Central Garden & Pet — One of the largest US suppliers of pet supplies and lawn/garden products, with brands like Kaytee (small animals and birds), FOUR Paws, Penn-Plax (aquatics), and Miracle-Gro's sister pet lines. It is a major private-label manufacturer for big-box retailers.

8. Spectrum Brands (United Pet Group) — Its pet division owns Tetra and Marineland aquatics, 8-in-1 (including Litter Genie), Nature's Miracle stain and odor removers, and Dingo dog chews. Spectrum is a powerhouse in aquarium and pet-cleaning categories.

9. KONG Company — The Colorado-based maker of the iconic red KONG rubber toy, one of the most recognizable pet products in the world. KONG's durable rubber toys are the default recommendation of trainers and veterinarians for enrichment and teething.

10. PetSafe (Radio Systems Corporation) — The leading US brand in electronic pet products: invisible fences, training collars, automatic feeders, and water fountains. PetSafe products are sold in 100+ countries and are the category benchmark for pet tech.

Sourcing Pet Products from US Manufacturers — If you are a retailer, distributor, or private-label buyer, the US pet market rewards quality certification: AAFCO feeding trials for food, FDA registration for food facilities, and ASTM/TPC safety standards for toys. US-made products also command premium pricing in export markets, especially in Asia and the Middle East.

The Private-Label Opportunity — Retailers like Chewy, Walmart, and Costco have built massive private-label pet programs, and contract manufacturers (many of them US-based) produce those store brands. For buyers, partnering with a contract manufacturer early can secure capacity and better margins than competing for branded distribution rights.

The US pet industry keeps growing because pet owners keep spending. Whether you are sourcing food, treats, litter, toys, or tech, the manufacturers above define the categories — study their product lines, and you will know what the market expects.
